ISO and Shutter Speeds
To get a picture of people in focus with a slow shutter speed to capture fireworks: Put on your flash. The flash will quickly lighten up the people while the shutter speed will capture the fireworks. (for those more technical it was set to 1st curtain sync which means it will flash first then stay open for the rest of the photo. If it was 2nd curtain flash which I like for single subjects, it will take the photo on the long shutter speed, then flash at the end. You will end up with less movement blur from people with 2nd curtain sync, but I play with both). I used BULB shutter speed and a remote and tripod when capturing fireworks.
SHUTTER SPEED CHALLENGE
You may need a tripod for these challenges.
If you are finding the photos are too light because you are taking them in the daytime, I will allow you to jump ahead in the lessons here, and switch your camera to manual mode. Put your ISO to 100, your F.Stop as a high number, and then set your slow shutter speed.
Use running water as your subject. Can be a fountain, a river, a waterfall or even water from a hose or tap and take a photo making the water blurred.
Take a photo of a night scene.
Take a photo that creates a sense of movement, e.g. waving a flag, ribbons, poi, dancing.
Take a photo while spinning the lens or pulling the lens in and out.
How was this photo taken? Notice the spinning background.
ANSWER: Using a flash (2nd curtain sync) with a slow shutter speed while spinning the lens.
